I am not looking to get very deep into listing parts and assemblies.  I would just like to list maybe 2 dozen tasks so that I could pull them up quickly to put on an estimate or invoice.  Such as:

Panel Change -  Blah blah description blah blah.  $Price
Vehicle Charger - Blah blah description blah blah.  $Price
New receptacle -  Blah blah description blah blah.  $Price

This is just a scope of work for the customer to see.  Many times I will end up just choosing "Electrical Work" and then typing in the description of that particular job myself.  But for the ones that I do often, iIwould like to be able to save them and pull them up quickly.

So I would make those tasks each it's own Item?

Could I delete all the items that are already there that I will never use?  Like Plumbing, HVAC, Building Sale, Reimb Group, etc?
